Answer:
Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value.
directional selection is a mode of natural selection is an extreme phenotype is favored over other phenotypes.
Disruptive selection describes changes in population genetics in which extreme values for a trait are favored over intermediate values.
Explain why a high ratio of surface area to volume benefits a cell.
Answer:
smaller single celled organisms have a high surface area to volume ratio cause surface area to the volume ratio smaller as the cell grows larger. if a sell grow beyond the limit not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume

Aaron is learning about genetics in science class, and he made a list about what he learned
. An example of a trait is blue eyes
Genes are always passed from offspring to parents
• Traits can be common and uncommon in populations.
. Genes determine most physical traits
Aaron made a mistake on his list. Which of these statements fixes Aaron's mistake
Answer:
Genes are always passed from offspring to parents
Explanation:
Well parents pass on genes to an offspring for one for another the parent will not always pass a gene for a certain trait on, if the trait is not a dominate gene it has the chance of getting replaced by the other parent's more dominate trait

Freshwater can be renewed, but environmentalists consider it nonrenewable. Why is there a contradiction in classification?
Freshwater is recycled through the use of irrigation, bathing, and everyday use.
Freshwater is easily polluted or depleted before it can be replaced.
Freshwater evaporates and condenses, and then precipitation returns it to the lakes.
Freshwater is highly affected by global warming, and is quickly evaporating.

You put a marshmellow on a metal coat hanger and roast the marshmellow over an open fire. The marshmellow catches on fire. You quickly blow it
out. Before you get a chance to eat it, your hand gets really hot where you are holding the metal hanger. What type of energy transfer can explain
this situation?
Answer: Conduction
Explanation: As the fire starts to heat up the metal hanger it transfers the heat onto your hand.
Conduction Def: The process by which heat or electricity is directly transmitted through a substance

Which statement accurately describes how genetic information is transferred during meiosis?
Meiosis creates four daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates two daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates four daughter cells that have identical genetic information to the parent cells.
Meiosis creates two daughter cells that have identical genetic information to the parent cells.
Meiosis is the reductional division which creates four daughter cells that have identical genetic information to the parent cells. Thus, the correct option is C.
What is Meiosis?Meiosis is a special type of cell division which is also called as reductional division. This division takes place in the germ cells in sexually reproducing organisms which results into production of gametes, such as sperm or egg cells. Meiosis involves two rounds of division which ultimately result in the formation of four cells with only one copy of each chromosome or half genetic content.
Meiosis is divided into two divisions: Meiosis I and Meiosis II. In which, Meiosis II is similar to Mitosis and Meiosis I involves the reduction of genetic material to half.
Therefore, the correct option is C.

What will be the phenotypes, and probabilities of their offspring?
Question 11 options:
75% purple and 25% white
100% purple
100% white
50% purple and 50% white
Answer:
75% purple and 25% white
Explanation:
When a punnett square is drawn to predict the phenotypes of the pea plants offspring:
- only 1 out of the 4 squares gave the result for the offspring to have white flowers (1/4 = 25%)
- 3 out of the 4 squares gave results for the offspring to have purple flowers (3/4 = 75%)

Question 9 options:
Box 1

Box 1 and box 3

Answer:
Box 1 and box 3
Explanation:
[tex]\huge\boxed{\textbf{Box 1 and Box 3}}[/tex]
_____________________________________[tex]\Large\textbf{Phenotype:}[/tex]
It is the physical appearance of the trait, whether the plant has Long stem or short stem.
[tex]\Large\textbf{Genotype:}[/tex]
A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or h o m o-zygous, recessive or dominant. This question is basically based on the Genotype, asking for the heterozygous plants which is a genotypic characteristic.
_____________________________________Alleles:Allele Long stem A is dominant over short stem a
Genotype of Parent Pea PlantsPea Plant 1 has genotype Aa
Pea Plant 2 has genotype aa
_____________________________________[tex]\Huge\text{Question:}[/tex]The question asks for how many heterozygous plants are present in the punnet square of pea plant 1 and pea plant 2.
Heterozygous PlantsHeterozygous Plants means those plants which have two different alleles that means One dominant allele (i.e. A here) and One recessive allele (i.e. a here). These Organisms inherit a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.
If we look at the punnet square given in the attachment, the Box 1 and 3 have genotype Aa which is a HETEROZYGOUS DOMINANT PLANT while box 2 and 4 have a genotype aa which is a HOMO-ZYGOUS RECESSIVE PLANT thus the answer is Box 1 and 3
